Application filed August 8, 1914. Serial No. 855,860:

To all whom it may concern.-

Be it known that I, LEE S. CHAnwIoK, a citizen of the United States,residing at East Cleveland,-in the county of Cuyahoga and State of.Ohio, have invented a certain new and useful Improvement in Oil-Stoves,

of which the following is a full, clear, and,

exact description, reference being had to the accompanying drawings.

This invention relates to oil burners, and more particularly to burnersof this type which are adapted to produce a flame suitable for use, in acooking stove. The various embodiments of the invention include a wickas the means whereby the oil is fed to the vaporizing point and wherebya vaporevolving surface is provided. The various forms of the inventionshown herein also relate to burners of the type whereina blue flame isproduced through the manner of supplying air to the vapors evolved fromthe upper and exposed end of the Wick and wherein, for this purpose, acentrally arranged air distributer of controller is pro vided within theupper end of the inner wick tube and a cooperating air distributer isprovided outside of the outer wick tube and between the same and thesurrounding an instance of such burners being drum, shown in the patentto Hoffman No. 1,092,262, issued April 7 1914:.

It is the general object of this invention .to improve the operation ofburners of this type and particularly in the matter of safety, renderingthe same practically immune from the dangerous conditions arising fromthedischarge of vapors about the lower ends of the wick tubes. These.vapors, catching fire, will generate vapors from-the wick tubes in suchquantity as to be incapable of proper combustion and control, While theheat produced by the combustion of the vapors about the bottoms of thewick tubes will break the connections in the oil supply to the wicktubes. whereby the. oil may be ignited at the points where such breaksoccur and the compartment in which the stove is located and the life ofthe operator be endangered thereby. W'it-h the foregoing general objectin view, the invention may be defined further as consisting of thecombinations of elements embodied in the claims hereto annexed andillustrated in the drawings forming part hereof, wherein Figure 1represents a vertical sectional view of a burner constructed inaccordance with my invention, including the lower portion of the drum orchimney; Fig. 2 is a transverse sectional view, with parts broken away,corresponding to the line 22 of Fig. 1; Figs. 3, 4. 5, and 6 arevertical sectional views of modifications of the burner shown in Figs. 1and 2.

Describing by reference characters the various parts illustrated hereinand with partieular'reference to Figs. 1 and 2, 1 denotes the inner and2 the outer wick tube of the burner, 3 a lateral supply connectionprojecting from the bottom of the outer wick tube and 4 a hook which. issecured to the inner wick tube, said connection and hook forming meanswhereby the burner may be connected to and the space between the wicktubes be placed in communication with the supply pipe (not shown) in themanner described in patent to'Jeavons 951,612 dated March 8, 1910. 5denotes the wick which is mounted within the space between the wicktubes, said wick being provided with a carrier 6 which is adapted to beengaged and operated by a wick raising wheel 7. The upper end of theinner wick 'tube is preferably bent or deflected outwardly, as shown at1, while the upper end of the outer wick tube is bent inwardly. as shownat 2. and then upwardly, as shown at 2", and the top of the inner wicktube the inner wick tube, this annular plate or ring forming a seat forthe air distributer' which is within the top of the inner wick tube.This distributor comprises a body (preferably hollow) which is mountedwith- "in' the upper portion of the inner wick tube,

said boi'ly'being preferably in the shape of two cone frustums placedbase to base and supported on the ring, whereby the lower the lastmentioned portion of the body forms'with. the top of the inner wick tubea passageway of diminishing cross sectional area from bottom to top, theupper portion of the distributer pro'ecting inwardly slig tly above thetop of the inner tube. at 9, is provided witha bottom 10, an invertedfrusto-conical wall-11, and a frusto conical wall 12 projecting upwardlyfrom wall. The-wall 11 is provided with a suitable number of outwardlyprojecting supporting :devices, shown as plates 13 four being shown),the lower ends whereof are adapted to rest upon the ring 8, the platesbeing preferably of such extent as to be in substantial engagement withthe inner wick tube, whereby the distributer wick - may be centered. .Itwill be observed that the passageway formed between the bottom portionof the distributer 9 and the inner minishing cross sectional area as faras the top portion 1' of 'thewick tube and that, from the bottom of thisportion'l the diminution in cross sectional area of the passageway,while uniform, served also'that the'plane of greatest width ofthedistributer 9 is slightly below of the wick, when the wick is inposition for normal operation.

.The outer wick tube is shown as provided with an outwardly projectingledge 14, which may conveniently be provided by doubling the metalthereof upon itself. On

the seat thus formed is supported the chimney or drum and the partswhich cooperate to distribute air to the exterior of the wick andtheexterior of the flame. 15 denotes a'vertical ring or collar whichsurrounds the upper portion of the wicktube, The bottom of this collaris shown as supported by the ledge 14 and the collar is cylindrical I incontour as far as the top of the outer wick tube, where it is flaredoutwardly, as shown at 16. The bottom of the collar preferably fits theouter wick tube closely, the

- portion of the collar which is opposite the this channel or troughparts, 2 'and 2 of the outerwick tube formingtherewith a trough orchannel 2. The part of the collar forming the outer wall for is providedwith 'a limited number of perforations 15* through which air may enterthe channel and, sweep ing upwardly, carry with itinto the flame aboveany vapors that may drop into the channel from the vapor of j the wickthereabove.

tion, there will be a slight space (about g -g inch) between the top ofthe flange and the wick. In the of the second air distributing element,a suitable number of large openings 19* will be provided, two horizontalseries of such openings being shown. In the lower portion of thecylindrical part 22 of this element a series of large perforations 22will be provided, said perforations being located below the flange 16.It will be evident that the first and second elements form in effect aunitary structure, both of which are supported byvthe ledge 14, and thata chamber is provided thereby which extends about the up er end of theouter wicktube.

he third element of tributer. comprises .a cylindrical body 24 of sheetmetal) which is of a diameter to enable it to be slipped over thecylindrical portioi 20 of the second distributing element an to enablethe body to be supported in engagement with the ,frusto-. conicalportion 19 of the second element. At its bottom, the third element isprovided with an outwardly projecting flange 25.v The upper end of thethird element is ex-v tendedupwardly and inwardly and is pref-.inn'eredge 27 preferably in vertical alinement with the inner edge 23ofthe element therebeneath. The downwardly and inwardly projec t ingportion of this third element is provided with perforations, as shown at26. The thirdelementprovides a passageway with the second element forconducting vapors and air into the space above the wick.

frusto-conical portion 19? With the burner operating in normal conditheexternalair disdrum 28 is preferably cy- I whereof may be formed into awire, as

will be shown at 30, the inner diameter of the wired portion being suchas to fit more or less closely about the cylindrical portion 24 of thethird air distributing element, the drum being supported by the flangeor ledge 25.

The inclined or inverted frusto-conical portion of the drum is providedwith perforations 29.

With the parts constructed and arranged as described, the operation willbe as follows: The wick being turned up to about the position shown inFig. 1 and ignited, vapor will be generated from the exposed top portionof the wick. Owing to the manner of supplying and distributing air, theflame,

a blue flame extending upwardly in the space between the top of the airdistributer 9 and the inner edges 23 and27 of the exteriorly arrangedoverhanging plates. When operating under ordinary conditions, there isliability that some vapor evolved from the outer -surface of the wickwill not be carried upwardly and will, in fact, fall downwardly aboutthe upper end of the wick tube. Such vapors will accumulate within thetrough 2 and will be carried thence upwardly into the flame by airadmitted through the openings 15 and 16.

In a'burner constructed as shown herein, the particular arrangement ofthe inner and outer distributers will secure an efiiciency which isgreater than that of any other burner of the particular type illustratedherein with which I am familiar. In operation, however, the wick. may beturned so high as to impinge against the lower edge 23 of the inwardlyextending distributer flange t-hereabove, or it may be brought intoundue proximity thereto. The flow of vap'ors from the major generatingportion of the wick will then be entirely cut oil or materially checked,as the case may. be. In either event, vapors evolved from the outerportion of the wick will fall by gravity. In all other burners of theparticular type shown herein with which I am familiar, these vapors willdrop into close proximity to the outer wick tube and, being ignitedthere, will evolve vapors from the wick tubes in such quantity as willproduce a flame which will not only be intensely smoky'but will beincapable of control. Furthermore, the continued burning ofvapors atthis point will loosen or break the connections between the supply pipeand the burner,

/ with attendant. danger of conflagration. By the constructionillustrated herein, should the operator happen to turn' the wick toohigh, the vapors evolved from the outer exposed surface of the wick willfall into the surrounding chamber and then be caught into the "flame.

when the wick is at normal height,

ring 8, and

lower portion 31 which may have a by the air flowing through theopenings 19 and swept through the openings 22 into the passagewaybetween the second and third elements of the external distributer and bedischarg d above the top of the wick and As a further precaution againstany inconsiderable quantity of va- I pors which might pass out throughthe openings 1 9 (the bottom wall 17 being imperforate) these vaporswill be caught by the air flowing upwardly through the openings 29 andabove the flame therein. Finally, should any vapors thus liberated fromthe external surface of the wick fail to be taken care of through thetwo passageways provided therefor, the flange 11 will discharge thesevapors at a point sufliciently remote from the wick tubes to prevent theundesirable consequences referred to hereinbefore, even if the vaporsshould be discharged in a sufficient quantity to.v produce a flame ofany material extent-a remote contingency.

In Fig. '3 there is shown a modification of the invention illustrated inthe preceding figures wherein the parts which are identical orsubstantially identical with those in the preceding figures are givenlike reference numerals. The inner and outer tubes, the; the bottom partofthe inner air distributer are identical in construction with the likenumbered parts in the preceding views, The upper part of the innerdistributer, instead of being frusto-conical, is shown as outwardlyconcaved, as shown at The collar or ring 15 is omitted in this.modification, and an outwardly and downwardly directed annular plate 17ismounted upon the outer wick tube and extends therearound in about thesamemanne-r as the plate 17 shown in Fig. 1. The outer portion of theplate 17 is provided with a vertical flange 17 and with a horizontalflange 17 therebeneath, the flanges forming a. seat for the lower wiredend of an external distributer element which is similar to the elementcomprising the parts 19 to 23 in the preceding view. In this case, theexternal distributing element comprises a cylindrical single series oflarge openings 32. The metal of this distributer element is shown asbent horizontally inwardly, at 33, and then upwardly in cylindricalform, at 34, the upper end being convex, as shown at 35, the extremeinner edge 36 of this convex portion being in the same positionwithreference'to the wick therebeneath as the edge 23 of the correspondingelement in the preceding modification. The cylindrical portion 34 is,shown as provided with a series of large openings 3%, corresponding tothe openings 22 in the preceding views. Outside oft-hedistributingelement just described is located another elementcorresponding to the eleand will be carried into the drum ment 24-27 inthe preceding figures. This element is shown as having a cylindricalportion 37, which is of a diameter to fit more or less closely upon thecylindrical portion 31 of the distributer element just described and towhich it may be permanently secured,

' as by peening the overlapping portions of the metal together, asindicated at 38. The bottom of the cylindrical portion 37 is shown asformed into an outwardly proj eoting flange 39 and the top of theelement isbent into convex form, as shown at 40, whereby it overhangsthe corresponding part of the element therebeneath and forms therewith apassageway which diminishes in cross sectional area to the dischargeoutlet formed between the alined inner edges 41 and 36.

Theinwardly projecting portion of the last described element is providedwith perforations, indicated at 62.

The operation of the burner disclosed in Fig. 4 will be substantiallythe same as that of the burner shown in the preceding views, except thatno perforations are provided enter the trough or chamber formed aboutthe outer exposed portion of the wick. Should the wick be turned undulyhigh, any

vapor evolved from the outer surface of the Wick will be directedoutwardly by the inclined wall 47 and will practically carried throughthe openings 54 into the passagewaybetween the plates 55 and 62 and bedischarged mainly through the slot between the edges 56 and- 63 into theflame. Some of' the vapors will bedischarged through the openings 62. Itwill be observed that, in this modification as well as vapor that mayoverflow through the openings, will be practically entirely caught bythedraft passing upwardly through the openings 59", and any thatmaynot-be carried through either of the separate paths thus provided, willbe discharged at a sufficient distance from. the burner to avoid danger,eve-n should they be present in a quantity suflicient otherwise to causesuch danger. 4

The outwardlyvprojecting flange 45 and the cylindrical portion 46 coiiperate to centerand support thereupon a sleeve which is substantially identical with thesleeve 50 in the preceding figure, which sleeve and its component parts.will be-numb'ered in like manner as in the preceding figure. At itsupper end, the sleeve is secured to a cylindrical portion of an airdistributer member which is similar to the member 5863 in Fig. 4. Thisdistributer member is preferably made from a. sheet metal plate and hasits outer edge provided with an upwardly projecting cylindr igal e plateis then shown as bent inwardly, at 65, to form a horizontal ring havingpe-rfora Thence it is shown as bent downwardly to form a cylindricalflange 66 to which the sleeve 50 may be secured, as by peening (see 66)From the bottom of the cylindrical part, the distributer plate is shownas projected inwardly and downwardly, at 67, being of substantially thesame shape as the part 62 in the preceding modification.
